Question
Give reasons for the following : Phenol is more acidic than ethanol.
Solution
The phenoxide ion, produced by losing of proton by phenol, is stabilised by resonance due to delocalisation of the negative charge on the benzene ring. Ethoxide ion, however, is not stabilised by resonance. On the other hand, it is further destabilised by positive inductive effect of alkyl group.
